2 Claims. (01. 158-99) This invention relates to a new and improved gasburner., Y

Fuel gas burners such as are commonly used in gas ranges are fixed inposition with respect to the range. It is the principal object of thisinvention to provide a burner that is adjustable both horizontally andvertically to attain a position that is most eihcient with respect tothat particular range or to the utensil that is being heated.

It is a further object of the invention to provide a burner having asingle discharge orifice, whereby the gas may be properly and completelyburned.

Further objects will appear to those skilled in the art from a readingof the specification.

Th accompanying drawings illustrate a preferred embodiment of theinvention. In these drawings:

Figure 1 is a side elevation, partially in section, of the new andimproved burner as applied to a gas range.

igure 2 is a plan view of the structure shown in Figure 1.

Figure 3 is a longitudinal vertical section, on an enlarged scale, ofthe new and improved gas burner.

Figure 4 is a representation, on a reduced scale tion of the flame whena utensil is being heated.

The new and improved burner comprises a horizontal tube 10 open at oneend it to receive the nipple i2 of a gas pipe l3. Th end H has adownwardly depending fiange M to aid in seating th tube to properly onthe nipple I2. The other end of the tube I terminates in an upwardlyextending diverging nozzle l6.

Depending from the tube ill, underneath the nozzle 16, is an internallythreaded sleeve I 8, which is adapted to receive the threaded stud IQ ofan adjusting screw 26. The adjusting screw 20 rests on a drip pan 22 orsimilar part of the gas range.

It will be apparent, therefore, that as the adjusting screw 23 isrotated in one direction or the other, the nozzle 1 will be raised orlowered with respect to the grate 24 on the top 'of the gas range. Themovement of the gas burner II) will center about the seat 54 that restson the nipple l2.

A ball-and-socket connection 26 is attached to the horizontal extremityof the nozzle 16 by means of a threaded cap 28, and a union 30 joins .iscompletely burned.

the connection 213 with a slotted rod 32. The slotted rod 32accommodates a set screw 34 that is secured in a bracket 35 fixed to thestove or range. The head of the set screw 35 is spaced I from thebracket 35 to permit vertical movement lei the slotted rod 32, asindicated in Figure l of the drawings.

Consequently, rotation of the union 30 will adjust the burner it)horizontally, the slot in the slotted rod 32 permitting movement at oneend, and the nipple l2 permittin movement at the other end. Theadjusting screw Zil'is, of course, not secured-to the drip pan 22, andslides along the surface thereof as th burner I0 is adjustedhorizontally.

In the operation of the device, operation of the adjusting screw 29 willvary the position of the orifice It with respect to the grate 24, thespacing of the head of the set screw 34 from the bracket 35 determiningthe extreme upper and lower limits of the vertical position of theorifice [6. Operation of the union 30 will vary the horizontal positionof the orifice l6, as hereinbefore indi- I cated.

orifice 16, the combustion of the gas will produce a single concentratedflame, as illustrated in Figure 4 of the drawings. When a pot is on thegrate 24, the flame will flow along the bottom of the pot and creep upthe sides, as indicated in Figure 5. The lateral distribution of theflame under the pot will pr-ovideaccess to a greater quantity of air, tothe end that all the fuel gas The horizontal and vertical adjustmentshereinbefore described permit positioning of the orifice IE to obtainthe most eificient combustion of the gas with respect to the particularutensil being heated. It is well known, of course, that the usual fuelburner does not permit any adjustment, so that the gas will be burnedmore or less completely, depending on the type of utensil being heated.This disadvantage is obviated by the new and improved burner herein setforth. It should also be mentioned that the quantity and pressure of gasare factors in determining the position of the orifice IS with respectto the utensil, it being an object of the invention to impinge thehottest portion of the flame against the bottom of the utensil.

A series of tests have demonstrated that the saving in gas consumptionaverages about onethird, and may approach one-half.

Where as the invention is shown as applied to a burner for fuel gas, itis apparent that it is equally applicable to other types of fluid fuels.

I claim:

1. A gas burner comprising a substantially horizontal tube having anopen inlet end to receive a horizontal gas supply nipple, the oppositeend of the tube being provided with a short upstanding tubular dischargenozzle, a depending extension secured to the bottom of the tube adjacentto the upstanding discharge nozzle and having a substantially verticalscrew threaded opening, a substantially vertical adjusting screwengaging within the screw threaded opening and adapted to rest upon afixed support and being adjustable to raise and lower the upstandingdischarge nozzle, a stationary support arranged substantially at theelevation of the tube and} ceive a horizontal gas supply nipple, thetube be ing provided adjacent to its opposite end with an upstandingtubular discharge nozzle, a depending boss secured to the tube near itsend having the upstanding discharge nozzle and having a substantiallyvertical screw threaded opening, a substantially vertical adjustingscrew engaging within the screw threaded opening and adapted to restupon a fixed horizontal support and turnable for raising and loweringthe end of the tube having the upstanding discharge nozzle, a fixedsupport arranged substantially at the elevation of the tube and spacedbeyond the end of the tube having the upstanding discharge nozzle, thetube being provided in its end having the upstanding discharge nozzlewith a ball socket, a ball swivelly mounted within the ball socket, atubular internally screw threaded sleeve secured to the ball andextending axially beyond the end of the tube having the upstandingdischarge nozzle, a screw threaded rod engaging within the screwthreaded sleeve and extending axially beyond the sleeve and toward thefixed support, the rod including a substantially flat head having alongitudinally extending adjusting slot formed therein, the headextending over and engaging upon the fixed support, and a screwextending through the slot of the head and adjustably connecting thehead to the fixed support.
